Happy Pi Day

I know this is a day late, but I think the following physics-based puzzle was the awesomest thing I saw on Pi-day (H/T Sol)!

This has to be the best problem I've seen so far this year!

Spoiler alert: the video contains an outline of the solution, but it us sufficiently vague to make you want to work it out anyway.
